IMPROVEMENT IN RAILWAY-TRUCKS ADAPTED To DIFFERENT GAGES'OF TRAKs.

Specification forming part of Letters Patent No. 43,163. dil-teil .lune lli, 1864.

To aZZ whom/-ib may cola/carni Be it known that LUHARLn-s D. TrsnALE rcsidentof East Boston, in the county of Suffolk and State of Massachusetts, have in. vented a new and-useful mechanism having reference to a railway-carriage constructed so as to enable the 4two wheels of each of 'its axles to bemoved in adirection either away from or toward each ,other, as circumstanceslnay require, in order to adapt the carriage to tracks of different gages; and I do hereby declare that the same is fully described in the following specification and represented in the accompanying drawings, of whichi f 'l Figure l isa-.top view of two wheels and one axle provided with my invention. 1 Fig. 2`

is a horizontal and 4 longitudinal sectionpand Fig. 3 a vertical andlongtudinal section, of

vthem; Fig. 4 isa 4top view of the lower'half of one of/the clutchboXes, hereinafter de- A scribed. Fig. 5 is an under side view of the `upper half of such clutch-box. Fig. 6 is a top View of the axle as separate from the wheels.

Fig. 7 is a transverse section vof the axleytaken through the stopper, which is at its middle. Fig. 8 is a transverse section of the axle, taken through one of the clutches. Fig. 9 is a transverse section of one ofthe clutch-boxesandv My invention isa new mechanism for locking each Vof the wheels in either of its positions on the axle, whether for a track of one gage .or for one' ot" different gage.

For the carrying outof my said vinvention each of the wheels A A should he applied to` the axle. B by inea-ns ot'a sleeve or tubular shaft, O, having the wheel fixedto it atgior near oneendof it, such sleeves-being madeto encompass-the axle B. .Each wheel A, with its sleeve or tubular `shaft 0shoul'd be capa- ,ble'of being slid longitudinally on .the axle,l and one of the shafts C and the axle mayhave a feather-connection, in order to prevent the hollow shaft Vfrom revolvingon the axle.y 'In other words, there maybesnch a feather connection or its equivalent to such shaft C, in which-case the other shaft would .be free to revolve on and independent-ly of the axle in, order to enabler its wheel to revolve either faster orl 'slower than the other wheel, as circumstances may rcqnire,lwhile thewheels may he traveling o'n a curved railwaytrack.

Such a feathercon'nection'consists of atongnc or rib, a, 'and a corresponding groove, I), the said tongue being made to project from the ax'le andi-nto the groove made longitudinally in the inner surface of the hollow shaft..`

In carrying ontV my invention I make use of a elntchboXD, to each tubular shaft C, and, furthermore, I employ a semicircular projection orclutch, Eto operate with the clutch'- box. The, clutch E is aii'ixed tothe axle B or projects from it and goes around it one hnndred and eighty degrees, or therea.bout,"and it is arranged a short distance fromwhat I term the"fstopper, F, which is placed at the middle of the shaft and formed asshown in thedrawings. There should be one Vof the `saidl clutches to "each clutch-box, and conse end of each of the sleeves or-tubnlar shafts C G. This latter flange H enters a correspond- 'in-gannular space, I, made in the clutch-box,

and serves not only'to connect the clutchlbox to the sleeve, but to allow the former to be revolved on the latter. i

Each clntohbox, as constructed, has a cylindrical chamber, K, formed within itthe diameter-of such chamber being equal to or a little greater than that of the' clutch. The

lower half of the chamber of the clutch-box has a semicircular flange, L, at its end which is next to the .stopper F. Furthermore, each half ofthe clutch-box is provided with a grooveor chamber,'M, of the forni shown in Figs. 4

wand-5, such grooves being for the reception of a boltforslider, N, which is formed as shown in Fig. 2, and more especially in Fig.- 10which is a top view of the bolt. This bolt enters both ofthe clutch-boxes and with the stopperoperates to determine the extent of rotaryr mot-ion of the clutch-boxes on the axle in order to enable them, to be moved over and nreceive the clutches or be drawnl oi the clutches, as circumstances may require. The bolt and stopper also serve to prevent the clutchboxes from being rotated on the shaft after the wheels may have been adjusted for any gage of a track. The stopperF has two shoulders, c c, and tw'o notches or recesscs,rl d, arranged track. Ou the ot the shoulders being such as to cause one of.

'them to estop the bolt, when it may be turned i with the clutch-boxes about the shaft and into i I claim- Y the proper position for moving the clutches lD either into or out of"the clutch-boxes. The

positiouof the-other shoulder c is such as to i scribed, and combining with the latter and jestop the bolt when the clutch-boxes arerevolved one hundred and eighty degrees froml the said position, in which case the4 clutches will be against .the semicircular flanges of' the clutch-boxes and will hold thewheel-shaft to the narrower gage. By revolving the clutchboxe's and their bolt ou'their axleuntil the bolt may be vbrought up against the proper shoulder 0, each of the clutch-boxes and its shaft C cau-be drawn away from the other clutch-box and-on the axle,.so as to separate the wheels for the broader track or. gage of ccomplishment of vthe movement of the Whg/els in directions apart from oneauother the clutch-'boxes and-the bolt should be' caused to make another semi-revolution on the shaft, in which case the clutchboxesgwill be in positions to prevent the Wheels from. being moved toward one'another.V The 'bolt has a notch, f, at `its middle, which rcceivesqthepart g of the stopperlwhilethe clutclr-boxesjand the bolt may be in the act of being turned around on the shaft. lThel bolt is also .provided withfou'r holes, hhh h'. Clherev v isfalso a hole, z',made through each clutchr 'boX, it being. so situated that a pin may be,

passed through it as Well asthroughcither'of theholes of the next adjacent halt' of thebol-t. By moving the bolt lengthwise into one of the notches d d and passing pins through holes of Athe two clutcliboxes and thebolt, the stopper will operate to prevent theV clutch-boxesvfrom within it,as shown in Fig. 7, the arrangement 'fbeing turned on'the shaft. '.Lhis can be done A whether the wheels are adjusted for the narrower or the wider track'.

1. The application of the Wheels to the axlel .by means ot' sleeves or tubular shafts, as dcthe axleA a means or' mechanismforxing the sleeves at different distances apart on the axle, inorder to adapt the wheels'to tracks of different gages, inlmanner as specified.

2'. The combination of the clutch-box D, the vflanges Gr H, and the semicircular clutch E,

3. The combination of the stopper F andythe bolt N, the two clutch-boxes D D, and their clutches EE, the whole being construe-ted and' applied to and so .as to operate with thefuaxle.

and the' wheelsleeves or hollow shafts, substantial-ly as hereinbetore explained. l

4. ,With the VWheels applied. to -the axlelby means ot sleeves or tubular shafts, as" described, and these latter and vthe axle provided.

with a means or vmechanism forv fixing the sleeves at diierent distances aparton the axle, and fon the purpose of adaptingthe wheels to tracks of different gages, the application of a feather connection-viz., the rib a and groove b-or its mechanical equivalent,to one of the sleeves only7 of the axle,.the othlr sleeve being free to revolve as welll as to slide on the axle.
